On a coordinate plane, an exponential function decreases from quadrant 2 into quadrant 1 and approaches y = 0. It crosses the y-axis at (0, 2.25)
On a coordinate plane, an exponential function decreases from quadrant 2 into quadrant 1 and approaches y = 0. It crosses the y-axis at (0, 0.44)
On a coordinate plane, an exponential function decreases from quadrant 2, through quadrant 3, into quadrant 4 and approaches y = negative 2. It crosses the y-axis at (0, negative 1)
On a coordinate plane, an exponential function decreases from quadrant 2 into quadrant 1 and approaches y = 2. It crosses the y-axis at (0, 3)
the correct option is:
"On a coordinate plane, an exponential function decreases from quadrant 2, through quadrant 3, into quadrant 4 and approaches y = negative 2. It crosses the y-axis at (0, negative 1)"
Which is the graph of the given function?
Here we have the exponential function:
g(x) = (2/3)^x - 2
Now, remember that for any real number different than zero, we have that:
x^0 = 1
So if we evaluate our function in x= 0 we will get:
g(0) = (2/3)^0 - 2 = 1 - 2 = -1
Then the function passes through the point (0, -1)
With this in mind, we conclude that the correct option is:
"On a coordinate plane, an exponential function decreases from quadrant 2, through quadrant 3, into quadrant 4 and approaches y = negative 2. It crosses the y-axis at (0, negative 1)"

write the standard form of the equation of the circle with the given characteristics. endpoints of a diameter: (3, 4), (−13, −14)
The standard equation of the circle will be (x+5)²+(y+5)²= 145
The center of the circle, which is the midpoint between those two locations, may be found first since you know the diameter endpoints.
formula for the midpoint
= ((x1+x2)/2, (y1+y2)/2)
Given points are - (3, 4), (−13, −14)
The circle's center is at (-5,-5)
Therefore, the circle's equation will take the form (x+5)²+(y+5)²=R², where R is the circle's radius.
The distance between a point on the circle and the circle's center in order to get the radius.
Therefore, let's calculate the distance between (-5, -5) and (-13,-14)
Radius R = √((-13+5)²+(-14+5)²) using the distance formula.
= 12.04
equation will be -
(x+5)²+(y+5)²= 145

Verify whether x = -1/√3 is a zero of the polynomial 3x²-1.
Answer:
Below.
Step-by-step explanation:
3x² - 1 = 0
3x² = 1
x² = 1/3
x = ±√(1/3)
= -1/√3, 1/√3.
So, -1/√3 is a zero of 3x² - 1 .
Yes, x = -1/√3 is a zero of the polynomial 3x² - 1 because substituting the value results in zero, confirming its solution to the equation.
To verify whether x = -1/√3 is a zero of the polynomial 3x² - 1, we need to substitute this value into the polynomial and check if it results in zero.
Given polynomial: 3x² - 1
Now, substitute x = -1/√3 into the polynomial:
3(-1/√3)² - 1
Now, simplify:
3(1/3) - 1
1 - 1
The result is zero. Since the expression evaluates to zero when x = -1/√3, this means that x = -1/√3 is indeed a zero of the polynomial 3x² - 1.

The measures are possible for the other two angles are 70 degrees respectively
Isosceles triangleAn isosceles triangle is a triangle that has 2 of its sides and angles to be equal.
Let the measure of the other possible angles be x and y such that x = y
Since the sum of angle in a triangle is 180 degrees, hence;
x+y +40 = 180
x+x+40=180
2x+40=180
2x=180-40

PLEASE HELP!! 80 PTS!! You research the cost of a gallon of gasoline over several years to look for a trend. The table shows your data. What is the equation for a line of best fit? How much would you expect to pay for a tank of gas in the year 2019? Let x be the number of years after 1998.
Answer: Because the initial value is $26.40, the line must pass through this when x is 0. Thus, the answer is either the first or the second equation.
Next, we calculate the difference between the year 2019 and 1998 and substitute it into the value of x.
2019 - 1998 = 21.
Substituting this into the equation:
y = 1.006(21) + 26.40
y = $47.52

Question :- Daisy is making solid spikes for her Halloween costume. the spikes are shaped like right circular cones with base radius of 2 inches and height of 6 inches. if daisy has 360 cubic inches of material for making the spikes, what is the maximum number of spikes she can make ?
Answer:- She can only create a maximum of 14 spikes.
Step-by-step explanation:
Given that :-
Daisy is making solid spikes for her Halloween costume.The spikes have a base radius of 2 inches and a height of 6 inches. They are formed like right circular cones.For creating the spikes, Daisy has 360 cubic inches of material.To find :-
maximum number of spikes made by her.According to Question,
We have,
base radius of the spikes = 2 inchheight of the spikes = 6 inchFor finding the maximum number of spikes,
We have to divide the volume of the material by the volume of the cone, for producing a maximum number of spikes.
So,
Maximum spikes = Volume of the material / volume of the cone
Now,
Volume of the material = 360 cubic inches
Volume of the cone = [tex]\frac{1}{3}[/tex] πr²h
Where:
r = radius = 2 in
h = height = 6 in
π = pi = 22/7
= [tex]\frac{1}{3}[/tex] × [tex]\frac{22}{7}[/tex] × [tex]2^{2}[/tex] ×6
= 3.14 × 4 × 2
= 25.12
So,
Maximum spikes = Volume of the material / volume of the cone
= [tex]\frac{360}{25.12}[/tex]
= 14.33
∴ The number of spikes must be an integer.
∵ Maximum spikes = 14.

What is a sequence of numbers?A sequence is series of objects that follow each other in a particular order.
a. The terms of sequence A are;
1/4, 1/2, 1, 2, 4
Therefore, each term is produced from the previous term by multiplying the previous term by 2 as follows;
1/4 × 2 = 1/2,
1/2 × 2 = 1
1 × 2 = 2
2 × 2 = 4
b. The values in sequence B are;
2, 12, 22, 32, and 42
Therefore, each term is produced from the previous term by adding 10 to the previous term as follows;
2 + 10 = 1212 + 10 = 2222 + 10 = 3232 + 10 = 42c. The definition of the nth term of sequence A is found using the formula for a geometric progression as follows;
nth term of a GP is; A(n) = a•r^(n-1)
Where;
a = The first term = 1/4
r = The common ratio = 1/2/(1/4) = 2
The nth term of sequence A is therefore;
[tex] A(n) = \frac{1}{2} \times 2^{(n-1)} [/tex]d. The definition of the nth term of sequence B is found using the formula for a arithmetic progression as follows;
nth term of a AP is; B(n) = a + (n-1)•d
Where;
a = The first term = 2
d = The common difference = 12 - 2 = 10
The nth term is therefore
B(n) = 2 + (n-1) × 10
e. The value of A(9) is therefore;
[tex] A(9) = \frac{1}{2} \times 2^{(9-1)} = 64 [/tex]
Which gives; A(9) = 64
